A remarkable distinction of classical to the quantum domain is the existence of the zero-point energy
[1]}. Feynman pointed out that the change in the zero-point
energies give rise to the Lamb shift in the atomic energy levels
[2]}. Similarly, the van dar Waals interaction occurs due to the
zero-point fluctuations. The vacuum fluctuations produce a non-vanishing
dipolar moment of the atoms [3]}. Hence a \(1/R^6\)  dependent
potential appears in the system. Here \(R\)  is the distance between the two
atoms. In the relativistic limit, the interaction is further modified by the
influence of the retardation effect [4]}. It is widely known as
Casimir-polder interaction (CPI). The force associated with this interaction
is known as the Casimir Polder force (CPF), for two parallel conducting plates, the force is attractive, and the expression of the force is given by, \(\delta F=-\frac{\pi ^2}{240 R^4}\) .
Several experimental verifications exist for the
CPI, which proves the Casimir physics as a hallmark in the quantum field theory
[5]}, [6]}. CPI is also used as an essential tool to
analyze local curvature effects in the presence of quantized fields
[7]}, [8]}, [9]}. In addition, a thermal character is
connected with the vacuum fluctuations of the quantized fields. It is commonly
known as the thermalization theorem, which tells that if a uniformly
accelerated particle detector interacts with the vacuum state of the external
field and spontaneous emission occurs, then the detector behaves as if it is in
a thermal bath [10]}. Hence the major implementation of Casimir
physics is shown in thermal-nonthermal scaling of a linearly accelerating atom,
interacting with a massless scalar field
[11]}, [12]}, [13]}, [14]}. One
major drawback of linear accelerating detectors is that the value of acceleration is
very large to produce 1K temperature [15]}. In contrast, Bell and
Leinaas identified that in a circular storage ring, one could produce a
relatively higher effective temperature within a shorter time-scale
[16]}. Unlike the uniformly accelerated detector, the rotating
detector cannot achieve a thermal state, as for the circular motion, there is
no existence of event horizon [17]}, [18]}. However, due to the
experimental efficiency of the moving electrons in the circular storage ring,
exploring Casimir-physics in the rotating co-ordinates is one of the developing
area in last few decades [19]}, [20]}, [21]}.
